In a payload process on a PS5 (firmware 12.70),
sysctlbyname("kern.rng_pseudo") answers a size query with 64 and gives
at most 64 bytes per call, up to a 65536-byte buffer. A buffer smaller
than 64 bytes gets as many bytes as its length and a null length gets
none, both with -1 and ENOMEM; a null buffer with a null length returns
0, and errno is kept when the call succeeds. Here the whole buffer was
filled, a size query threw and the length was never changed. The 64
random bytes are now drawn only for a read that passes both a buffer
and a length.

About
Tool for automatic executables porting to Linux and Windows.
The relinker-only build runs on macOS, including Apple silicon.
Web converter - files stay on your device.
Includes a relinker that converts executable to the target system's native format and implementations of system prx libraries suitable for dynamic linking. No emulation or separate runtime process.

Status
* System libraries: percentage of the functions known to the project so far (declared in core/libs/prx), not of every PS5 system function. The total grows as more functions are declared.
Unsupported or unexpected states strictly throw std::runtime_error. what() is printed to stderr and the process terminates.
The shader recompiler successfully produces SPIR-V (validated via Spirv-Tools when built with ANYPS5_ENABLE_SPIRV_TOOLS).
Compatibility
Per-game progress (stage reached, open blockers, libraries and GPU coverage) is tracked on the blocker map, a community project built from public GitHub data (source). Test reports go in the Game bring-up discussions, one thread per title.
Input mapping
SDL-mapped game controllers are supported, including analog sticks and triggers. Keyboard and mouse controls can be configured with an anyps5-input.ini file. See input mapping for the supported devices and configuration format.
